By what kind of mechanisms do we perceive the physical world beyond ourselves? What is the relation between perceptual processes and natural evolution? What is the nature of a perceptual state? In this thesis I discuss traditional inference theories of perception. These views have suggested that perceptual processes resemble rational processes of inference or computation. I compare traditional inferentialism with Bayesian perceptual science. In The Origins of Objectivity (2010) Tyler Burge argues that perceptual science makes non-trivial use of representational notions. Perceptual states constitutively represent a physical world beyond the individual. I present this view in light of the previous discussion. Finally, I explore whether the perspectival feature of perceptual representation suggests that they are subjective experiences.
